Title: Magnetic head support arm assembly
IPC: G11B5/48
Filed: 1975-05-21
Abstract: 1464059 Support arms for magnetic heads INTERNATIONAL BUSINESS MACHINES CORP 21 May 1975 [22 Aug 1974] 21873/75 Heading G5R A support arm assembly for a magnetic head supports the head from a central finger 36 of a flexure 22 connected to one end of a stiff element 10 which is connected at its other end to a rigid support 14 by a spring plate 20, flexure 22 having two resilient fingers 32a, 32b which are parallel to finger 36 and to the length of element 10 and are located one to either side of the finger 36 which extends towards support 14 from connections to those ends of fingers 32a, 32b furthest from support 14, finger 36 including a protuberance (40), Figs. 2 to 4 (not shown), in contact with a further part 24 connected to stiff element 10. A magnetic-head-carrying air bearing slider 38 is supported at the lower side of finger 36, the protuberance (40) being at the centre of gravity of slider 38. The stiff element 10 is triangular with flanges forming channels along two sides and is integral with spring plate 20 and with flexure 22. A triangular load beam 24 resting in said channels has an end part 29 bearing on protuberance (40), beam 24 being welded at 27 to element 10 to stiffen the latter. Fingers 32a, 32b are joined by resilient cross-legs 34a, 34b, the finger 36 being resilient and extending from leg 34a towards leg 34b but not engaging the latter, Fig. 3. In use spring plate 20 has the effect of resiliently loading slider 38 towards a record disc. The contact point between part 29 and protuberance (40) serves as a pivot point for slider 38 allowing pitch and role movements thereof, such movements being taken up by the resilience of legs 34a, 34b and fingers 32a, 32b respectively without effecting the position of protuberance (40). The stiffness of element 10 resists movements of slider 38 radial and circumferential to the disc and also yaw movements. In an alternative assembly, Figs. 7, 8 (not shown), the slider-supporting finger (52) is rigid rather than resilient.

Abstract: 1,114,847. Cathode ray tubes. RADIO CORPORATION OF AMERICA. 24 May, 1965 [12 June, 1964], No. 21928/65. Heading H1D Electrons overscanning a shadow mask electrode in a colour television tube are prevented from penetrating into the gap between the supporting frame of the electrode and the faceplate sidewall by a shield in the form of a strip of metal foil having a pair of flanges extending along its length, one flange being secured to the electrode, and the other being pressed directly against the sidewall to conform closely thereto by the spring action of the portion of the metal foil strip intermediate the two flanges. Beam electrons overscanning the rectangular mask electrode 30, which includes a peripheral frame 28 supported from the faceplate sidewall 20 by four leaf-springs 33, each engaging a corresponding stud 24 mounted in the sidewall 20 at the mid-point of each side of the frame, are prevented from penetrating into the gap between the frame and the sidewall by the foil strip shield 34. The strip is held in position by crimping spaced tabs 40 over the inner rim of the flange 32 of the electrode frame, the outer flange 38 being thereafter pressed, either manually or by use of a tool, to conform to the sidewall 20. Away from the vicinity of the stud 24 the foil may be pressed into a U-shape extending deep into the gap (Fig. 19, not shown), which provides a spring action maintaining the outer flange 38 tight against the sidewall. The shield may be in the form of four separate strips overlapping at the corners of the faceplate, and is of aluminium or steel, preferably coated, on the surface furthest from the sidewall and the frame, with a black ceramic, to enhance the rate of radiation and minimize the rise in temperature of the mask electrode.

Abstract: 480,104. Knitting-machines. JACKSON, T., and UPHILL, K. M. Aug. 12, 1936, No. 22201. [Class 74 (ii)] A multi-feeder circular machine is provided with means for repeating at one or more feeders 13, 14 the selection of needles made at a previous feeder 12 without using patterning mechanism at the later feeders 13, 14. The invention is described in connection with a cylinder-and-dial rib machine in which patterning is effected by the cylinder needles only, and involves the use of pattern jacks 23 which are rocked by pattern controlled levers 18 but are held against longitudinal movement. Jacks 5, interposed between the jacks 23 and the needles, are selected at the feeder 12 by levers 18 and a pattern drum 15, so that some are pressed inwardly and are not raised by a. cam 24. To maintain the selection at the feeders 13, 14, jacks 5 which are not raised by the cam 24 have their butts 7 guided by a cam 28 so as to be held down while passing the feeders 13, 14. At the feeder 11, all the needles may be raised to clear their loops.. To allow the jacks 5 to be drawn down freely by the cam 28, they are modified by dispensing with the normal stop butts 29.

Title: Improvements in and relating to electric motor control systems
IPC: B60L15/20
Filed: 1950-09-13
Abstract: 721,584. Control of D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd., and CARTER, H. F. Aug. 27, 1951 [Sept. 13, 1950], No. 22528/50. Class 38 (3). A vehicle is driven by an electric motor M having a series field winding SF and a shunt field winding S, accelerating resistances R1, R2, R3, being connected in series with the armature of the motor. When a master controller is moved to its first position, contact P1 is closed to energize contactors 1A, 1, and to connect the motor to the line through contacts 1<SP>1</SP>, 1A<SP>1</SP>. Interlock 1A<SP>11</SP> closes to energize contactor 5, so closing contact 5<SP>1</SP> and energizing the shunt field winding to provide low-speed operation of the vehicle. Movement of the master controller to a second position closes a contact P2 to energize cyclically-operated relays T1, T2, T3, in turn. This sequential operation is due to the fact that energization of relay Tl opens contact T1<SP>1</SP> to remove a shortcircuit from the coil of relay T2, whilst energization of relay T2 opens contact T2' to remove a short-circuit from the coil of relay. T3. When contacts T2" close, contactor 2 is energized and contacts 2' remove resistor R1 from the motor circuit, whilst contacts 2<SP>111</SP> de-energize the contactor 1. Energization of relay T3 opens contact T3" to prevent further cyclic operation of the relays T1, T2, T3. However, when the master controller is moved to its final position, contacts P3 are closed to short-circuit the relay coil T1, and, after a period of delay, the relay Tl drops to recommence the cyclic operation of the relays. The de-energization of the relay Tl closes contacts T1<SP>11</SP>to energize contactor 3 and close contacts 3<SP>1</SP>, so short-circuiting resistors R1, R2. When the relay T2 drops after a further delay, the contactor 1 is re-energized. The contactor 4 is energized to remove a further portion of the armature resistance when the relay T3 drops. Relays Tl, T2, T3, are then successively energized, the contactors already closed being retained by interlocks. When the relay T1 drops at 'the start of another sequence, the contactor 2 is re-energized to connect the motor directly across the supply. The opening of relay T2 partially diverts the series field winding and opens the shunt field circuit. When the relay T3 opens, the series field winding is fully diverted. The control sequence may be halted by moving the master controller to its second position or by the intervention of a current-limit relay. After contacts P1, P2, P3, have been opened, braking is instituted by closing contacts Bl and B1', the shunt field winding being energized and a resistor connected across the armature of the motor and the series field winding.
